Yes, this problem is known (it is actually in the client) but is a little tricky
to fix. 

Basically the sftp client does a realpath() to verify that a path is accessible
and to change relative paths into absolute ones, but realpath breaks on traverse
only directories. 

The solution is to modify the client to fall back to doing a stat() on the path
when the realpath() fails. The client can then just continue, using a relative path.

This isn't particularly nice either, because it adds another round-trip for each
"cd" command (only on realpath error though)
